ROTARY FLUID-MOTOR.

SPECIFICATION forming part of Letters Patent No. 509,644, dated November28, 1893.

Application filed February 11 1893. $erial No. 461,857. (No model.)

To aZZ whom it may concern.-

Be it known that I, EDWARD E. EARDSLEY, a citizen of the United States,and a resident of Philadelphia, Pennsylvania, have invented a certainImprovement in Rotary Fluid-Motors, of which the following is aspecification.

One object of my invention is to construct a rotary fluid motor of anextremely cheap and simple character compared with its effiro c1ency,andone which can be run in either direction at will, a further object beingto provlde for the ready changing of the direction of rotation of themotor. These objects I attain in the manner hereinafter set forth, ref-[5 erence being had to the accompanying drawlugs, in which Figure 1, isa perspective view of a fluid motor constructed in accordance with myinvention. Fig. 2, is a plan view of the same,

partly in section; and Figs. 3, 4t and 5, are sectional viewsillustrating different forms of motor wheel or disk which can beemployed.

My improved fluid motor consists of a disk A secured to a shaft B whichis mounted in suitable bearings so as to be free to turn, the diskhaving upon its outer edge a projecting flange a which is, bypreference, bent inward slightly at the top, as shown in Fig. 3. Thecentral portion of the disk may be in the form 0 of spokes or openworkif desired, and the disk may run either horizontally, vertically or atan angle.

Above and at one side of the disk A is a conical nozzle D which ispreferably mounted upon the depending end of a fluid supply pipe Fsothat it can be turned thereon, the hub or butt 1) of the nozzle beingprovided with a handle cl for this purpose The nozzle D is so disposedthat the jet 4o therefrom will be delivered parallel with a linetangential to the periphery of the disk A and will strike the surface ofsaid disk close to the outer flange, the force of the water beingexerted upon the disk and flange and the stream spreading upward on saidflange to which it clings by reason of capillary attraction until it isfinally discharged by centrifugal force over the edge of the flange, asshown in Fig. 1. The water is thus caused to act upon the disk andflange throughout a corn siderable portion of the entire circumferenceof the disk so thatIam enabled to obtain almost as high a degree ofpower as in a bucket motor operated by a jet, especially in cases wherethe jet is very small and issues with great velocity from the nozzle.

One important advantage possessed by my improved motor over the ordinaryform of bucket motor, moreover, is that it is capable of being runeitherbackward or forward with equal facility, by simply changing thedirection of the jet, and in order that this latter result may bereadily accomplished I use a pivoted nozzle as shown in Fig. 1, whichwhen adjusted to the position shown by full lines in Fig. 2, will drivethe motor disk in one direction, and when adjusted to the position shownby dotted lines in said figu re, will drive said disk in the oppositedirection.

In carrying out my invention various forms of flange may be formed uponthe disk A in place of that shown in Figs. 1 and 3. For instance, aninwardly curved flange such as shown in Fig. l may be used, or a lowupturned flange, such as shown in Fig. 5, or in some cases the flangemay be dispensed with altogether, as I have obtained good results from amotor in which the jet was simply discharged upon the face of a fiatdisk, the use of the flange in all cases, however, being preferred, asit serves to confine the water to the disk for a longer time and thusenables it to exert a greater amount of power than if it were not soconfined.

It will be evident that, in carrying out my invention, there can be twoor more nozzles disposed so as to discharge upon the disk at differentpoints, and the jets can all act upon the same face of the disk or someupon one face and some upon the opposite face of the same, and in othercases there may be more than one disk upon the shaft, each of the disksbeing acted upon by one or more jets.

In some cases, also, the face of the disk may be slightly roughened orprovided with fine 5 corrugations, but these should not be such as tobreak up the jet or cause any rebounding of the water on striking thedisk.

Having thus described my invention, I claim and desire to secure byLetters Patent-- I00 1. A fluid motor consisting of a disk or plate anda nozzle located above the plate but inclined downward toward the same,and also occupying a position parallel with a line tangential to theperiphery of the plate so that it will discharge downward upon the faceof the plate, adjacent to the periphery of the same, a jet parallel tosuch tangential line, substantially as specified.

2. A fluid motor in which are combined a disk or plate having anupturned flange upon its outer edge, and a nozzle located above theplate butinclined downward toward the same, and also occupying aposition parallel with a line tangential to the periphery of the plate,whereby it will discharge downward upon the face of the plate, adjacentto the periphery of the same and within the flange, a jet parallel tosuch tangential line, substantially as specified.

3. A fluid motor in which are combined a disk or plate, and a nozzlelocated above the plate but. inclined downward toward the same, saidnozzle being pivoted to the supply pipe and capable of being movedthereon to right orleft so as to occupy, when in either extreme ofmovement, a position parallel with a line tangential to the periphery ofthe plate, substantially as specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
